Question 1

What is DNS Cache?

Accepted Answer

A DNS cache is a temporary storage area for recently accessed domain name records. When you visit a website or access any internet service, your computer first checks its local cache for the domain name's IP address. If it finds a match, it uses that information to connect you with the destination server quickly.

The DNS system maintains this cache of recently accessed domain names and their corresponding IP addresses, which speeds up subsequent queries. However, over time, this cache may become outdated or corrupted due to various reasons such as websites changing their IP addresses, network problems causing incorrect information to be cached, or security programs blocking legitimate access. In such cases, clearing the cached data can solve many problems related to internet connectivity.

Question 2

Why flush DNS Cache?

Accepted Answer

Flushing DNS cache is an essential step in resolving network issues related to domain name resolution. DNS cache is a temporary storage area for recently accessed domain name records. It is designed to speed up subsequent queries by translating human-readable domain names into IP addresses. However, over time, the cached information can become outdated or corrupted due to various reasons such as websites changing their IP addresses, network problems causing incorrect information to be cached or security programs blocking legitimate access.

Clearing DNS cache can solve many problems related to internet connectivity. When you clear the cached data, your computer starts fresh and creates a new cache with up-to-date information. This process helps your computer connect quickly and accurately with the destination servers, resulting in faster browsing and improved overall internet experience.

Flushing DNS cache is easy and quick, but it varies slightly depending on the operating system or distribution being used. With this guide's help, you can clear your DNS cache with confidence in just a few simple steps.
